Abstract
Abstract A connector for use with a ribbon cable grounds alternate conductors of a fine pitch ribbon cable, and allows selected conductors associated with the connector signal contacts to be grounded. The connector is readily adaptable to differing grounding configurations. The connector includes a plurality of signal contacts housed within an insulative body. The signal contacts electrically connect to alternate individual conductors (the "signal conductors") of the ribbon cable. A first ground bus is electrically connected to the conductors of the ribbon cable which are not connected to a signal contact (the "ground conductors"). A second ground bus electrically connects selected conductors of the signal conductors with the ground conductors. By altering the second ground bus, the grounding scheme of the connector can easily and quickly be altered. A latching cover is provided for securing the ribbon cable to the connector body and against the signal contacts, the first ground bus and the second ground bus.
